Agreed. You really have to keep the 547 "on the boil" so to speak.
Not unlike Toni Zimmer's Honda S2000 I drove. About 6500-9400 is when the REAL power shows up. And when it does, it's a beautiful thing.
I've driven some older Fiat twin-cam small engines in the X19 and the Lancia Scorpion. They like to rev, but no torque.
Have you ever driven a 2.0 litre 911? Same thing, but a touch more torque because flat6.
